<h2 id="details">详细信息</h2>
<p>The <a href="qsgbasicgeometrynode.html">QSGBasicGeometryNode</a> class serves as a baseclass for geometry based nodes.</p>
<p>The <a href="qsgbasicgeometrynode.html">QSGBasicGeometryNode</a> class should not be used by itself. It is only encapsulates shared functionality between the <a href="qsggeometrynode.html">QSGGeometryNode</a> and <a href="qsgclipnode.html">QSGClipNode</a> classes.</p>
<p><b>Note: </b>All classes with QSG prefix should be used solely on the scene graph's rendering thread. See <a href="qtquick-visualcanvas-scenegraph.html#scene-graph-and-rendering">Scene Graph and Rendering</a> for more information.</p></div>
